ELECTRIC VACUUM CLEANER BACKGROUND OF THE INVENTION The present invention relates to an electric vacuum cleaner.
An electric vacuum cleaner which is transformable depending on places to be cleaned is disclosed in Japanese Unexamined Utility Model Publication No. 80455/1992, wherein the electric vacuum cleaner is of concurrent type which can be used in an upright condition for use by fastening a vacuum cleaner body to a support pipe in a attachable/detachable manner and which can also be used in a condition where the vacuum cleaner body is detached from the support pipe.
Such a conventional concurrent type vacuum cleaner comprises, as shown in Fig. 21, a vacuum cleaner body 31, a hose 40, a support pipe 32, a rotary bend 33 and a suction device 34. By sequentially connecting these components, there is achieved a condition where the vacuum cleaner body is detached from the support pipe wherein the vacuum cleaner body 31 and the support pipe 32 20 are separated.
The rotary bend 33 is connected to the suction device 34 (or a rotary pipe (not shown) connected to this suction device 34) in a rotatable manner.
Further, by fitting projections 36 provided on the outer surface of the support pipe 32 to concave portions 35 formed on the lower surface of the vacuum cleaner body 31, the lower surface of the vacuum cleaner body 31 can be fastened to the support pipe 32, whereby the vacuum cleaner can be transformed into an upright condition for use as shown in Fig. 21. When assuming the upright condition for use, the vacuum cleaner body 31 is leaning against the support pipe 32 and abuts onto the suction device 34. In the upright condition for use, the hose 40 is so arranged that the upper end thereof is connected to a position substantially below a grip 37 in the rear side of the support pipe 32, an intermediate -2portion thereof is vwinding from the side of the support pipe 32, and the lower end thereof is connected to the vacuum cleaner body 31 in the front side of the support pipe 32. It should be noted that 31a denotes a portion at which rear wheels 38 at a rear portion of the lower end of the vacuum cleaner body 31 are provided.
There are formed at least two concave portions on the lower surface of the vacuum cleaner body 31 along a front and rear direction of the vacuum cleaner body 31, and a plurality of projections 36 are provided VA along a vertical direction of the support pipe 32 so as to correspond to the respective concave portions However, according to this conventional art, the front and rear wheels of the suction device and the rear wheels of the vacuum cleaner body contact the ground in the upright condition for use. Since six wheels simultaneously contact the ground in this arrangement, change in running directions when performing cleaning operation is hard to be made, whereby the cleaning I 20 workability is made poor. It is further presented a drawback, in a condition where the vacuum cleaner body is detached from the support pipe, that the rear wheels of the vacuum cleaner body largely project rearward and look unattractive.
A conventional vacuum cleaner is also arranged in such a manner that the rotary bend 33 can be rotated with respect to the suction device 34 in the upright condition for use. In addition, the center of gravity of the vacuum cleaner body 31 attached to the upper surface of the support pipe 32 is located above a rotating axis (that is, a position corresponding to a central axis of a connecting portion 39 of the rotary bend 33 and suction device 34).
Therefore, when the support pipe 32 and rotary bend 33 are slightly inclined to a vertical direction in Fig. 21 as to rotate with respect to the suction device 34, continuous force in a rotating direction is applied to an users hand holding the grip 37 in the upper portion of 3 the support pipe 32 and is thus quite unstable which also leads to poor Workability.
On the other hand, while this problem can be solved by an arrangement in which the rotary bend 33 is preliminarily fastened to the suction device 34 so that it cannot rotate, such an arrangement would limit the sphere of usage and be undesirable, since, for instance, the suction device 34 can no longer be inserted into narrow spaces such as under a bed in which the rotary bend 33 is in a condition where it is rotated as far as to be parallel to the floor surface with the vacuum cleaner body being detached from the support pipe.
The conventional electric vacuum cleaner of Fig.
21 also presents a drawback that it is difficult to fix the vacuum cleaner to the support pipe since the plurality of projections 36 aligned in the upper and lower ends of the vacuum cleaner body need to be simultaneously fitted to the concave portions Further, during the detaching process, the 20 vacuum cleaner body 31 might loose its stability in a case where only the projection 36 on the lower side is fitted to the concave portion 35, since the front side of the vacuum cleaner body 31 would then not be fixed to the support pipe 32.
c i.i t25 A conventional vacuum cleaner in its upright condition for use is so arranged that a portion in the proximity of the upper end of the hose 40 projects from below the grip 37 to rearward the support pipe 32. This 3 arrangement presents a drawback that the vacuum cleaner body is hard to use since this portion contacts the user of the hose 40 in a rubbing manner.
The present invention has been made in view of solving these problems, and it is an object of the present invention to provide an electric vacuum cleaner having improved cleaning workability and a vacuum cleaner body of improved external appearance when it is detached from the support pipe.
It is further an object of the present invention 4 H to provide an electric vacuum cleaner which can be easily operated in an upright condition for use by preventing the rotary bend which use by p re e t ine t h e otary bend which receives the load of the vacuum cleaner body from rotating relative to the rotary pipe at a side of the suction device, and moreover, of which sphere of usage is not limited by ermitting rotation in a condition where the vacuum cleanr body is detached from the support pipe.
It is also an object of the present invention to provide an electric vacuum cleaner of which vacuum cleaner body can be easily attached to/detached from the support t pipe.
Itis 1ULprover oanjet of the present invention to provide an electric vacuum cleaner in which the stableness of the vacuum cleaner body during the attaching/detaching process is improved.
It is still another object of the present invention to provide an electric vacuum cleaner in which the hose in the upright condition for use can be smoothly operated without contacting the user.

5 a rotatable manner, and a suction device to be connected to the rotary pipe, wherein the vacuum cleaner body is arranged such that the vacuum cleaner body can be fastened to the support pipe 5 in a detachable manner and wherein the electric vacuum cleaner is provided with a rotation regulating means for preventing rotation of the rotary pipe with respect to the support pipe when the vacuum cleaner body is attached to the support pipe.
10 In accordance with the present invention, there is also provided an electric vacuum cleaner of the present invention comprising: a vacuum cleaner body, a support pipe connected to a suction inlet of 15 the vacuum cleaner body, a rotary bend connected to the support pipe, a rotary pipe connected to the rotary bend in a rotatable manner, and a suction device connected to the rotary pipe, 20 wherein the vacuum cleaner body is attached to the support pipe in a attachable/detachable manner, and wherein the electric vacuum cleaner further includes a rotation locking means for locking rotation of the rotary bend with respect to the rotary pipe when the vacuum 25 cleaner body is attached to the rotary pipe at a specified position.
The rotation locking means preferably comprises a flat portion formed on the vacuum cleaner body, a flat portion formed on the rotary bend, and a flat portion formed on the rotary pipe.
It is preferable that at least a part of the flat portion of the rotary bend and the flat portion of the rotary pipe is so formed as to project from a circumferential surface of the rotary bend or rotary pipe 35 along a tangential direction of the circumferential surface.
The rotation locking means preferably comprises projections formed on the rotary bend and the rotary pipe,

In accordance with the present invention, there is still further provided an electric vacuum cleaner comprising a vacuum cleaner body, a hose to be connected to the vacuum cleaner body, a support pipe to be connected to the hose, and a suction device to be connected to the support pipe, wherein the support pipe is provided with a first engaging portion which detachably engages with a first receiving portion formed in a rear portion of the vacuum cleaner body, and a second engaging portion which detachably engages with a second receiving portion formed in a front portion of the vacuum cleaner body.
The second engaging portion of the support pipe is preferably movable up and down.
It is preferable that a tip portion of the second engaging portion of the support pipe is formed with a slanting surface that is inclined in an upward direction with receding from the support pipe.
It is preferable that the electric vacuum cleaner includes an energizing means that energizes the second engaging portion of the support pipe in a downward direction.
In accordance with the present invention, there is yet further provided an electric vacuum cleaner comprising a vacuum cleaner body, a hose to be connected to the vacuum cleaner body, a support pipe to be connected to the hose, and a suction device to be connected to the support pipe, wherein the vacuum cleaner body is detachably fastened to a front of the support pipe, and wherein the hose is connected to the vacuum cleaner body and the hose in the front of the support pipe.

It is preferable that a grip is fastened to a rear side of the bent portion of the support pipe.
Since the electric vacuum cleaner of the present invention is provided with running wheels at its suction device and the vacuum cleaner body is made to run by the wheels of the suction device in a condition where the vacuum cleaner body is attached to the support pipe, the cleaning workability is favorable.
Since the electric vacuum cleaner of the present invention includes a rotation locking means for locking rotation of the rotary bend with respect to the rotary pipe, the rotation locking means locks the rotation between the rotary pipe and rotary bend by making the vacuum cleaner body abut against the rotary pipe at a specified position when transforming to the upright condition for use. Therefore, the support pipe and the rotary bend cannot be inclined as to rotate with respect to the suction device. Accordingly, no force in a rotating direction is applied to an users hand holding the 20 grip at the upper portion of the support pipe.
When transforming to the condition where the vacuum cleaner body is detached from the support pipe, rotation locking condition between the rotary pipe and the rotary bend can be released by simply separating the vacuum cleaner body from the rotary pipe at the specified position. Therefore, the rotary bend can be rotated so as to be parallel with respect to the floor surface so that the suction device is inserted into a narrow space such as under a bed in a condition where the vacuum cleaner body is detached from the support pipe.
The electric vacuum cleaner of the present invention is so arranged that concave portions are formed at end portions in the front and rear of the vacuum cleaner body, and on the other hand, convex portions are formed at the support pipe and the like corresponding to the concave portions, as to be aligned in a vertical direction, and as to be opposing to each other (i.e.
downward facing convex portion being positioned above 1

8 upward facing convex portion). Moreover, the downward facing convex portion of the support pipe is movable up and down- By these characteristics, it has been enabled in the electric vacuum cleaner of the present invention, when being transformed to the upright condition for use, that the downward facing concave portion at the rear end of the vacuum cleaner body is made to fit to the upward facing convex portion formed, for instance, at the support pipe, and thereafter, the upward facing concave portion at the front end of the vacuum cleaner body is made to fit to the downward facing convex portion of the support pipe which might, for instance, be a clamping hook Vice versa, when detaching the vacuum cleaner body from the support 15 pipe, the above-described processes are performed in a reverse manner. Therefore, fitting and separation of the concave portions and convex portions can be sequentially performed point by point.
When the downward facing convex portion comprising a clamping hook is pushed up for detaching the vacuum cleaner body from the support pipe, the vacuum cleaner body is likely to tumble in a direction apart from the support pipe with a position at which the concave portion at the rear end fits with the upward facing convex portion being as a fulcrum. In this case, the additional provision of the hose connecting the vacuum cleaner body and the support pipe and arrangement of a hose retainer for fixing the hose at a higher position than the downward facing convex portion of the support pipe would fix the vacuum cleaner body to the support pipe through the hose and the hose retainer, whereby tumbling of the vacuum cleaner body can be prevented.
The electric vacuum cleaner of the present invention is further so designed that the electric vacuum cleaner body and the upper end opening of the support pipe are arranged on the front side of the support pipe, and that the hose connecting the electric vacuum cleaner body and the upper end opening is arranged in the front of the di s a ii I f 1 10 I :20 upport pip racuum clea or use, si .n the rear

S I DETAILED DESCRIPTION The electric vacuum cleaner of the present S invention will -now be explained in details with reference to the drawings.
The electric vacuum cleaner of the present 11 invention is an electric vacuum cleaner of concurrent type which can be used in an upright condition for use (see Fig. in a condition where the vacuum cleaner body 1 is detached from the support pipe 2 (see Fig. 13), and in a handy condition where only the vacuum cleaner body 1 is used (see Fig. 12), by making a vacuum cleaner body 1 to be detachably fixed to a support pipe 2.
The electric vacuum cleaner shown in Figs. 1 to 8 comprises a vacuum cleaner body 1, a support pipe 2, a rotary bend 3, a rotary pipe 4, a suction device 5, and a i hose 6 for connecting an upper end opening 2a of the support pipe 2 with a suction inlet la of the vacuum cleaner body 1. The suction device 5 is provided with running wheels W, and in the above described upright condition for use, running of the electric vacuum cleaner Sis enabled by these running wheels W.
A grip 7 to be held by an users hand is fastened to an upper portion of the support pipe 2.
As shown in Fig.2, an upper end opening 3a of the rotary bend 3 is connected to a lower end opening 2b of the support pipe 2. The support pipe 2 and the rotary bend 3 are connected to each other in a attachable/detachable manner as not to be rotatable by means of a C-ring 30 to be described later (see Fig. 25 As shown in Fig. 7, an upper end opening 4a of the rotary pipe 4 is connected to a lower end opening 3b of the rotary bend 3 in a rotatable manner. The rotary bend 3 and the rotary pipe 4 are connected to each other as to be rotatable but not to be detachable by means of a locking piece 8 (see Fig. More particularly, a circumferential groove 4b (see Figs. 7 and 8) is formed at a circumferential surface in an upper portion of the rotary pipe 4. On the other hand, a pair of opposing rectangular openings 3c are provided in a lower portion of the rotary bend 3. The rotary bend 3 and the rotary pipe 4- are connected to each other so as to coupie the-- above groove 4b and the rectangular openings 3c (see Fig. and thereafter, the locking piece 8 is fitted to the iM I P *t the r 1 ~wL~ ~prrP~ ra~om~~ 12 rectangular openings 3c in such a manner that a tongue piece 8a of the locking piece 8 is arranged in the interior of the groove 4b. With this arrangement, the rotary bend 3 and the rotary pipe 4 are connected to each other as to be rotatable but not to be detachable.
As shown in Figs. 4 and 5, the suction device is connected to a lower end opening 4c of the rotary pipe 4. The suction device 5 is connected thereto so as not to be rotatable with respect to an axial direction of the rotary pipe 4. In this embodiment, a hollow rotary shaft 9 is fastened to the lower end opening 4c of the rotating pipe 4, and both ends of the rotary shaft 9 are connected to a rear portion of the suction device 5 in a rotatable manner. With this arrangement, the rotary pipe 4 is enabled to move around the rotary shaft 9 with respect to the suction device As shown in Figs. 2 to 4, a lower surface lb of the vacuum cleaner body 1 can be fastened to the outer surface of the support pipe 2 in a detachable manner.
The method of fixing according to this embodiment is as follows: a downward facing concave portion Ic (a first receiving portion) of Fig. 3 formed at a rear end of the lower surface lb of the vacuum cleaner body 1 is fitted to an upward facing convex portion 4d (a first I. 25 engaging portion) of Fig. 2 provided to the rotary pipe 4, whereby a condition of Fig. 4 is assumed. Then, by making the vacuum cleaner body 1 abut against the support pipe 2, a downward facing clamping hook 10 of Fig. 2 provided to the support pipe 2 is fitted to an upward facing concave portion Id (a second receiving portion) of Fig. 3 formed at a front end of the lower surface lb of the vacuum cleaner body 1. In this manner, the lower surface lb of the vacuum cleaner body 1 can be fastened to the outer surface of the support pipe 2 as shown in Fig. 1.
As shown in Fig. 16, the clamping hook areleasingpi0c comprise s 1Oa 7 and a claw portion (a second engaging portion) that are linked by a pair of linking plates lOc.

13 The pair of linking plates 10c are arranged to be respectively parallel to the compression coil spring 51 in a manner as to sandwich the compression coil spring 51 from vertical directions in Fig. 16. Further, an upper end of the compression coil spring 51 abuts against a spring stopper 52 fastened to the support pipe 2. The spring stopper 52 is arranged between the pair of linking plates 10c.
S
p l The clamping hook 10 can move up and down in an interior of a cover 53 fastened to the support pipe 2.
When transforming the electric vacuum cleaner according to this embodiment into the upright condition for use, the downward facing concave portion Ic at the rear end of the vacuum cleaner body 1 is first fitted to the upward facing convex portion 4d at the rotary pipe 4 as shown in Fig. 4. -ted Thereafter, the vacuum cleaner body 1 is rotate with a point at which the concave portion Ic and the convex portion 4d are fitted being as a fulcrum, and the S 20 upward facing concave portion Id at the front end of the vacuum cleaner body 1 is fitted to the clamping hook 10 of the support pipe 2.
In this embodiment, a slanting surface 10d which is inclined in an upward direction with receding from 25 the support pipe 2 is formed on the claw portion 10d of the clamping hook 10 as shown in Fig. 16. Thus, by simply rotating the vacuum cleaner body 1 to a direction in which it abuts against the support pipe 2, an end edge If of the concave portion ld of the vacuum ceaner body 1 pushes the clamping hook 10 up while contacting the slanting surface and thereafter, when the entire claw portion lOb has Sgot over the end edge If, it will fall into the interior of the concave portion Id. Consequently, fitting of the concave portion ld and the clamping hook 10 can be easily 35 performed. It should be noted that while the present __embodiment--has-beeen explained-by aing an example in which a slanting surface 10d is provided, the present invention is not limited to this, and fitting of the
I
.1 14 concave portion Id and the clamping hook 10 can be performed also without the slanting surface 10d but by manually operating the releasing pinch 10a up and down.
Moreover, since the clamping hook 10 is energized downward by the compression coil spring 51 in this embodiment, the fitting of the concave portion Id and the clamping hook 10 can be made even firmer. It should be noted that while the present embodiment has been explained by taking an example in which a compression coil spring 51 is employed as an example of an energizing means for energizing the clamping hook 10 downward, the present invention is not limited to this, and an elastic member such as rubber might be employed as an alternative energizing means to make the fitting of the concave portion ld and the clamping hook 10 even firmer. It Sshould be further noted that fitting of the concave portion ld and the clamping hook 10 can also be performed by drop of the clamping hook 10 by its own weight, without providing an energizing means.
Next, detaching the vacuum cleaner body 1 from the support pipe 2 can be performed by carrying out the processes as described above in a reverse way,- that is, the clamping hook 10 is drawn out from the concave portion ld by sliding the releasing pinch 10a of the ciamping hook 25 10 upward and performing detachment by the remaining processes in a reverse way. Therefore, since fitting and separation of the concave portion Ic and the convex portion 4d as well as the concave portion ld and the clamping hook 10 can be sequentially performed point by point, attaching/detaching of the vacuum cleaner body 1 can be easily performed.
'When pushing the clamping hook 10 up for detaching the vacuum cleaner body 1 from the support pipe 2, the vacuum cleaner body 1 is likely to tumble in a direction apart from the support pipe 2 with a position of Sthe concave portion lc at the rear end fitting to the -upward facing convex portion 4d being as a fulcrum.
However, since the hose retainer 49 for fixing the hose 6 1 j Q L; r 15 connecting the vacuum cleaner body 1 and the support pipe 2 to the support pipe 2 is arranged at a higher position than the clamping hook 10 as shown in Fig. 1, tumbling of the vacuum cleaner body 1 can be prevented by the tension of the hose 6 after fixing the hose 6 to the support pipe 2 by means of the hose retainer 49.
A rotation locking mechanism 14 is shown in Figs. 2 to 5 which is the rotation locking means according to this embodiment for locking the rotation of the rotary bend 3 with respect to the rotary pipe 4 when the vacuum cleaner body 1 is abutted against the rotary pipe 4 at the specified position. This rotation locking mechanism 14 comprises a flat portion 11 formed on the lower surface lb of the vacuum cleaner body 1, a flat portion 12 formed in 15 the proximity of the connecting portion between the rotary pipe 4 and the rotary bend 3 on the outer surface of the rotary bend 3, and a flat portion 13 formed in the proximity of the flat portion 12 of the rotary bend 3 on the outer surface of the rotary pipe 4.
As shown in Fig. 2, at least a part of the flat portion 12 of the rotary bend 3 and the flat portion 13 of the rotary pipe 4 are made to project from the circumferential surface of the rotary bend 3 or the rotary J pipe 4 along a tangential direction of the circumferential surface, the surface areas of the flat portions 12, 13 are made wide. Therefore, these can more easily and reliably contact the flat portion 11 on the side of the vacuum cleaner body 1.
When transforming the electric vacuum cleaner of the above described arrangement into the upright condition for use, the vacuum cleaner body 1 is made to abut against the rotary pipe 4 at the specified position by engagement between the concave portion Ic and the convex portion 4d.
By this operation, both the flat portion 12 of the rotary bend 3 and the flat portion 13 of the rotary pipe 4 are S* made to abut against the flat portion 11 on the side of i |the vacuum cleaner body 1, whereby the rotation between the rotary pipe 4 and the rotary bend 3 can be locked.
I J 16 Therefore, the support pipe 2 and rotary bend 3 cannot be inclined as to rotate with respect to the suction device 5. Consequently, no force in a rotating direction is applied to an users hand holding the grip 7 on the upper portion of the support pipe 2.
Even in a case where the rotary bend 3 is at a somewhat distorted position with respect to the rotary pipe 4, this distortion is automatically corrected, since the rotary bend 3 faces to the front such that the flat portion 12 is parallel to the flat portion 11 on the side of the vacuum cleaner body 1 when making the vacuum cleaner body 1 abut against the rotary pipe 4. The cl damping hook 10 can thus be easily fitted to the upward I facing concave portion Id on the upper surface of the vacuum cleaner body 1.
S On the other hand, when transforming to a condition where the vacuum cleaner body 1 is detached from the support pipe, detaching the vacuum cleaner body 1 from S :the rotary pipe 4 at the specified position causes the flat portions 12, 13 separate from the flat portion 11, whereby the rotation locking condition between the rotary pipe 4 and rotary bend 3 is released to enable free rotation (see Figs. Therefore, when rotating the rotary bend 3 by approximately 90 degrees as to be parallel to the floor surface as shown in Fig. 5(b) in a condition where the vacuum cleaner body is detached from the support pipe, a full-flat condition as shown in Fig.6 is assumed and the i suction device 5 can be inserted into narrow spaces such as under a bed.
It should be noted that while the present embodiment has been explained by taking an example in which the rotation locking mechanism 14 comprising the flat portions 11, 12 and 13 is employed as the rotation locking means for locking rotation between the rotary bend 3 and the rotary pipe 4 in the upright condition for use, the present invention is not limited to this, and it goes without saying that a rotation locking means of another Damr

~PY~CC~P
17 type might also be employed.
An alternative type rotation locking means might be a type in which projections are formed on the rotary bend 3 and the rotary pipe 4 which are fitted to concave portions formed on the vacuum cleaner body 1.
In the electric vacuum cleaner according to this embodiment, improvements have been made in that exhausted gas from the side surface of the vacuum cleaner body is not directed to the user in none of the upright condition for use (see Fig. in the condition where the vacuum cleaner body is detached from the support pipe (see Fig.
13), or in the handy condition (see Fig. 12) as shown in Figs. 9 to 13.
There has been conventionally known electric vacuum cleaners which are capable of being used in two conditions, that is, an electric vacuum cleaner which can be concurrently used in an upright condition and in a handy condition, and an electric vacuum cleaner which can be concurrently used in an upright condition and in a condition where the vacuum cleaner body is detached from the support pipe. Both of them are provided with exhaust outlets at proper positions to exhaust gas into proper directions. In the case of the exhaust outlet is provided on the side surface on the upper portion of the vacuum cleaner when in the upright condition for use, wherein exhausted gas is directed to the user, and in the case of the exhaust outlet is provided on the front surface on the lower portion of the vacuum cleaner body, wherein exhausted gas is directed to the side opposite to the user.
However, it has not been known for an electric vacuum cleaner which can be used in three conditions as that of this embodiment, and applying either of the exhaust outlets of case or would cause inconveniences that, in either of the three condition for use, the user would be exposed to exhausted gas or exhausted gas would fling up dust.
In order to solve these problems, the exhaust e~~iloeora~as8pa~ pu-W~"-s~ 18 outlet 21 of the vacuum cleaner body 1 according to this embodiment is of slit-type which is inclined diagonal-rearward when seen from the side of the vacuum cleaner body 1 as shown in Figs. 10, 12 and 13, and a section of the vacuum cleaner body seen from the upper surface side of the vacuum cleaner body 1 (a horizontal 13 section of the vacuum cleaner body 1) is open to diagonal-frontward with respect to the vacuum cleaner body 1 as shown in Fig. 9.
Moreover, the exhaust channel in the interior of the vacuum cleaner body 1 is so arranged as shown in Fig.
9 that exhausted gas is once sent to the rear of the vacuum cleaner body 1 from rearward of a motor 22 and exhausted from the side in a winding manner.
As shown in Fig. 9, exhausted gas which is exhausted from the motor 21 is made to flow rearward of the motor 21 downward in Fig. separated into two directions and made to flow to a spaced portion 24 lying between an outer wall le of the vacuum cleaner body 1 and a rib (separating wall) 23 provided between the outer wall le and the motor 22. The exhausted gas is turned over in the spaced portion 24 and is exhausted to diagonal-frontward (diagonal-upward in Fig. 9).
Thereafter, exhausted gas is guided diagonal-frontward at 25 a specified angle by a guide rib 25 of a diagonal-forward inclined shape and the slit-shaped exhaust outlet 21.
As shown in Fig. 10, the slit-shaped exhaust outlet 21 is open in a diagop.al-frontward inclined shape when seen from the side of the vacuum cleaner body 1, whereby exhausted gas is exhausted to diagonal-upward as indicated by arrow B.
Thus, the user who is on the right-hand side with respect to the vacuum cleaner in Fig. 10 will not be exposed to exhausted gas in the upright condition for use shown in Figs. 10 and 11 so that the vacuum cleaner can be -comfortably used without flinging up any dust on the floor i surface.
In the handy condition of Fig. 12, the vacuum

cleaner body 1 is used in a condition where the suction inlet la is facing downward, but the user who is on the right-hand side with respect to the vacuum cleaner body 1 in Fig. 12 would not be exposed to exhausted gas so that the vacuum cleaner can be comfortably used without flinging up any dust on the floor surface.
Further, in the condition where the vacuum cleaner body is detached from the support pipe as shown in Fig. 13, the vacuum cleaner body 1 is used in a condition where the suction inlet la is directed horizontally, but the user who is on the right-hand side with respect to the vacuum leaner body 1 in Fig. 13 would not be exposed to exhausted gas so that the vacuum cleaner can be comfortably used without flinging up any dust on the floor srace. It should be noted that the number of parts can be decreased by integrally forming the exhaust outlet 21 for guiding direction of exhausted gas with the vacuum cleaner body 1 (especially on the lower portion in Fig.
The present embodiment is further arranged in that a C-ring 30 is employed as a bend setting ring for enabling easy attaching/detaching between the support pipe 2 and the rotary bend 3, between other pipes or between a pipe and a hose as shown in Figs. 2, 14 and 15, wherein the C-ring 30 is always fitted to a groove 25 formed on the surface of the support pipe 2.
In the present embodiment, a C-ring 30 which is a ring applied with a so-called C cut is employed as shown 30 in Figs. 14 and 15. By abutment of the rotary bend 3 against the C-ring 30 when the rotary bend 3 is fitted to the support pipe 2, the C-ring 30 is once lifted in an automatic manner from the surface of the support pipe 2 and is enabled to perform a returning action by elasticity (spring characteristics) of the C-ring Moreover, the C-ring 30 is so arranged that the C-ring 30 is always fitted to the interior of the groove 25 formed on the outer surface of the support pipe i i k 1__1~ 20 Ii 2. The inner surface side of the C-ring 30 is provided with a convex portion 30a which projects into the interior of the support pipe 2 through a hole 25a formed on the bottom surface of the groove 25. Therefore, when fitting the rotary bend 3 to the support pipe 2, the convex portion 30a can be caught by the groove 25 as shown in Fig. 15(b) even if the C-ring 30 is once lifted from the surface of the support pipe 2, whereby the C-ring 30 is prevented from falling from the support pipe 2.
By the above described arrangement of the C-ring and the groove 25, when performing fitting of the rotary bend 3 to the support pipe 2, the rotary bend 3 might be simply inserted into the support pipe 2 from a condition shown in Fig. 14(a) without touching the C-ring 30. That is, by the convex portion 30a pressing to the outer surface of the rotary bend 3, the C-ring 30 is once lifted from the surface of the support pipe 2 (see Fig.
and thereafter, the C-ring 30 is returned onto the surface of the support pipe 2 by elasticity thereof while the convex portion 30a fits to the rotary bend 3e, whereby fitting between pipes can be performed without gripping the C-ring 30 by hand.
On the other hand, when removing the rotary bend 3 from the support pipe 2, the C-ring 30 is pinched 25 by hand, and the concave portion 30a is caught at the interior of the groove 25 as described above, which enables detachment of the rotary bend 3 without the C-ring completely being detached from the support pipe 2.
In the electric vacuum cleaner shown in Figs. 1 and 4, the lower surface lb of the vacuum cleaner body 1 is fixed to the front side of the support pipe 2 in a freely detachable manner by a fixing method which will be described later. Further, the upper end opening 2a of the support pipe 2 is formed on the front side of the support pipe 2. The hose 6 connecting between the vacuum cleaner body 1 and the support pipe 2 is arranged on the front side of the support pipe 2 over its full length. Due to this arrangement, the hose 6 does no longer contact the S*i -i

i As shown in Fig. 1, at least a part of the upper portion of the support pipe 2, for instance, a bent portion 2b in the upper portion of the support pipe 2, is bent to the front side of the support pipe, and the upper end opening 2a is formed on the upper end of the bend portion 2b of the support pipe 2, the hose 6 to be connected to the upper end opening 2a can still further be receded from the user, which enables easier operation.
Moreover, since a grip 7 is fixed to the rear side of the bent portion 2b, the grip 7 can be easily held by hand and can further be easily operated.
Further, as shown in Fig. 17, the electric vacuum cleaner according to this embodiment is so arranged that the hose 6 is provided as to be symmetrical with respect to the vacuum cleaner body 1 and the support pipe 2 when seen from the front of the electric vacuum cleaner 20 in Fig. 17, there are no differences in operability between a right-handed person and a left-handed person.
Moreover, since the electric vacuum cleaner according to this embodiment is so arranged that internal components of the vacuum cleaner body 1 such as motor 22 which might influence weight balance are also arranged symmetrically when seen from the front of the electric vacuum cleaner as shown in Fig. 9, there are no differences in operability between a right-handed person and a left-handed person. It should be noted that numeral 21 in Fig. 9 denotes an exhaust hole formed in the outer wall le of the vacuum cleaner body 1, 23 a rib, 24 a spaced portion and 25 a rib for changing the flow of exhausted gas.
As shown in Figs. 1 and 18, the electric vacuum cleaner of the present embodiment also has improvements in an accommodation portion of attachments for efficiently utilizing the available space.
Attachments such as a crevice nozzle have ~r~8~sen~arpr~apas~sa~- 22 conventionally been accommodated into housing portions formed by denting the rear portion of the vacuum cleaner body or by attaching a separated housing of ring-shape or cylindrical-shape to the vacuum cleaner body or to the proximity of the grip. However, when accommodating them into the rear portion of the vacuum cleaner body, the accommodating position of the attachments will be low, which is troublesome since the user needs to squat down each time attachments are to be attached/detached. On the other hand, in the latter case, addition of a separate element for accommodation would be necessary and would also require additional space.
By the arrangement of accommodating attachments such as crevice nozzle 43 in a space between a pair of opposing code racks 41a, 4lb provided in the rear side of the support pipe 2 for winding up a power supply code 42 as shown in Figs. 1 and 8, space can be efficiently utilized. An additional element for fixing the attachments can be eliminated and provision of the attachments accommodating portion close to the grip 7 enables easy operation.
As shown in Fig. 18, by engaging a lower end of the crevice nozzle 43 to a triangle rib 44 projecting 'upward from the code rack 4lb and by fitting a S* 25 semi-spherical projection 45 projecting from both sides of an upper end of the crevice nozzle 43 into a hole 44a of a triangle rib 44 projecting downward from the code rack 41a, the crevice nozzle 43 can be accommodated between the code racks 41a, 41b. Further, by providing ribs 46, 47 on the outer surface of the support pipe 2 located between the code racks 41a, 41b, space can be secured between the crevice nozzle 43 and the support pipe 2 which enables it to easily detach the crevice nozzle 43.
When using the electric vacuum cleaner in the 35 upright condition for use as shown in Fig. 1, the power supply code 42 is used by untying it from the code racks 41a, 41b. At this time, the power supply code 42 might be disturbing when extending in the proximity of the users iW

'xl ii ICIII*^_~QP- 23 feet. In the present embodiment, by making the power supply code 42 engage with the grip 7 in a attachable/detachable manner, the power supply code 42 would not disturb the user. More particularly, at least a pair of claw portions 48 are provided in an opposing manner in the interior of the grip 7 for holding the power supply code 42. By engaging the power supply code 42 with the claw portions 48, the power supply code 42 draws a loop and reaches the ground with the grip 7 being the start point as shown by the two-dot chain line of Fig. whereby the feet of the user are not disturbed and easy operation is enabled. It should be noted that the claw portions 48 might be provided as a different member from the grip 7.
According to the present invention, the suction device is provided with running wheels, and the vacuum cleaner body is made to run by using these wheels of the suction device in a condition where the vacuum cleaner body is attached to the support pipe, whereby the cleaning workability can be improved. Further, the external appearance of the vacuum cleaner body in a condition of being detached from the support pipe can be improved.
In the upright condition for use, the rotary bend which receives the load of the vacuum cleaner body is 25 prevented from rotating relative to the rotary pipe on the side of the suction device, whereby no force in a rotating direction is applied to the users hand holding the grip, and operation is made easy.
Moreover, by enabling rotation between the rotary bend and the rotary pipe in the condition where the vacuum cleaner body is detached from the support pipe, the suction device can be inserted into narrow spaces such as under a bed so that the sphere of usage is not limited.
Further, according to the present invention, 'aftaching/detaching of the vacuum cleaner body to/from the -support pipe is made easy whereby operation is made by far 1 easier.
By arranging the position of the hose retainer frs;tB~eL~ee~o~ls~P~ap~l~~ pear -24more higher than the upper engagement position of the vacuum cleaner body and the support pipe, stability of the vacuum cleaner body during the attaching/detaching processes of the vacuum cleaner body can be improved.
Further, according to embodiments of the present invention, the hose would not contact the user and can be smoothly used in the upright condition for use. Since the hose would not contact the user, the user would also not feel uncomfortable and is able to comfortably perform cleaning.
Unless the context clearly requires otherwise, throughout the description and the claims, the words 'comprise', 'comprising', and the like are to be construed in an inclusive as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to".
